If your top load washer smells bad, start by cleaning the washer with hot water and vinegar. Check for mold, mildew, or residue buildup. Ensure proper ventilation and avoid overloading the washer. If the smell persists, inspect the drain pump and hoses for clogs or damage.

Confirm the symptom

• Unpleasant odor coming from the washer
• Musty or sour smell when opening the lid
• Bad smell even after running a cycle
• Visible mold or mildew inside the washer
• Residue buildup on the washer's surfaces

• Baking soda
• Old toothbrush
• Screwdriver (if needed)
• Towels
• Ensure the washer is unplugged
• Turn off the water supply to the washer

Step-by-step troubleshooting

1. Clean the Washer
   Do: Pour 2 cups of white vinegar into the washer's detergent dispenser. Add 1/2 cup of baking soda directly into the washer tub. Run a hot water cycle.
   Observe: Check for any visible mold, mildew, or residue buildup.
   Means: This helps to eliminate odors and kill bacteria.
   Next: If the smell persists, proceed to the next step.
2. Clean the Dispenser
   Do: Remove the detergent dispenser and soak it in hot, soapy water. Use an old toothbrush to scrub away any residue.
   Observe: Check for any clogs or buildup.
   Means: This ensures that detergent is properly dispensed and doesn't cause odors.
   Next: Reassemble the dispenser and run another hot water cycle with vinegar.
3. Check the Door Seal
   Do: Inspect the door seal for mold or mildew. Clean it with a mixture of vinegar and water.
   Observe: Look for any signs of damage or excessive wear.
   Means: A clean seal prevents odors and ensures proper washing.
   Next: If the seal is damaged, consider replacing it.
4. Inspect the Drain Pump
   Do: Locate the drain pump (usually at the bottom front of the washer). Check for clogs or debris.
   Observe: Listen for any unusual noises during operation.
   Means: A clogged pump can cause odors and poor draining.
   Next: If the pump is clogged, clear the debris and test the washer.
5. Check the Hoses
   Do: Inspect the water inlet and drain hoses for kinks, cracks, or blockages.
   Observe: Ensure proper water flow and no leaks.
   Means: Damaged hoses can cause odors and water issues.
   Next: If hoses are damaged, replace them with new ones.
6. Ensure Proper Ventilation
   Do: Make sure the washer has adequate ventilation around it.
   Observe: Check for any obstructions or tight spaces.
   Means: Good airflow helps prevent mold and mildew growth.
   Next: If the smell persists, consider professional help.
7. Avoid Overloading
   Do: Follow the manufacturer's guidelines for load sizes.
   Observe: Ensure the washer is not overloaded during cycles.
   Means: Overloading can lead to poor cleaning and odor buildup.
   Next: If the problem continues, seek professional assistance.
